I was in BTS with my family last weekend and we were attracted to their outlet there by the large crowd and deco. I had the seafood congee and as you have commented it was watery. The roast duck was hard and tasteless while the pork ribs were hard and salty. The noodles were soft, not springy and had a strong flour taste. The steam glutinous rice was just ok but nowhere near that from Marco Polo. Overall the food was way below expectations.
I doubt we would go back again and I would not recommend it to my friends.
